GPSMAP® 431/431s

The GPSMAP 431 is a compact chartplotter that features an ultra-bright 4” QVGA color display along with an improved high-speed digital design for increased map drawing and panning speeds. It’s ready to go with a built-in, satellite-enhanced basemap preloaded with U.S. Inland Lakes and an easy-to-use interface designed to help you navigate the open waters with ease. The GPSMAP 431 also accepts BlueChart® g2 Vision cards for added features and functionality such as high-resolution satellite imagery, 3D views and Auto Guidance technology.

Navigate the Lake
The GPSMAP 431 comes ready to go with preloaded U.S. Inland Lake map data. For areas outside the U.S., the GPSMAP 431 has a worldwide basemap with satellite images in place of more traditional maps. The GPSMAP 431 also comes standard with a high-sensitivity GPS receiver for superior satellite tracking and quicker acquisition times. And with an SD card slot, it’s easy to add additional maps without connecting to a computer.

Add Sonar
Where applicable, the sounder version, GPSMAP 431s, comes with a powerful dual-beam transducer that clearly illustrates depth contours, fish targets and structure whether you’re fishing in freshwater or off the coast. The GPSMAP 431 and GPSMAP 431s are also NMEA 0183-certified for easy connectivity with sensors, instruments and future marine offerings.

Add Extras with Inland Lakes Vision
With the optional Inland Lakes Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.

• 3D Mariner’s and Fish Eye view provides you with a 3-dimensional perspective of map information, both above and below the waterline
• High-resolution satellite images to help you orient yourself in unfamiliar areas
• Auto Guidance technology searches through all relevant charts to create a route you can actually follow
   — one that avoids obstacles, shallow water, buoys and other obstructions
